Taking an 8-head high-precision peanut oil medium packaging filling machine as an example, the filling capacity is 10L – 25L, production capacity is 720 – 960 barrels/hour, accuracy reaches ±2‰, power supply is 380±10% V, air source pressure is 0.4 – 1.0MPa, and the equipment specifications are 340017502420mm. This device combines years of production experience and is independently developed, using high-precision metering pumps, with high filling accuracy, speed, and wide range. It features automatic bottle mouth clamping (more accurate bottle mouth positioning), internal transfer tank (eliminating the pressure difference in the oil filling liquid level, more stable filling accuracy), and more. It utilizes Siemens PLC from Germany, with one head and one pump flow pressure stable and non-interfering with each other, double-section independent conveyor belts allowing filling and capping to operate independently, and a belt-type capping machine that is stable and reliable without air pressure phenomena, suitable for quantitative filling of various edible oils, lubricants, and other oil products, and can adapt to different materials such as PET, PE plastic barrels.
